To all whom it may comme; 1 Be it known that l, Wimmer E. BLACK- fsfroim, a citizen of the United `Sta-tes, resid Aing at Buchtel, county of Athens, and State of Ohio, have invented certain new and useful .Improvements in Pumping Apparatus, #of which the following is aspeciiication. My invention lrelates to pumping apparafp.; tus and particularly .to such apparatus as is lo especially adaapted for pumping-fout suinps or other pits in which water accumulates.

In operating mines it is customary to Y. provide numerous sumps in which the water @or` moisture in the mine will accumulate sind topro-vidc suitable pumping; apparatus for "drawing ofi" the watervvhich ae i nulates.

The object @tiny invention is Ao provide enimprovedI pumping epjperetus :tor the Epurpose mentienedwliicli shall automatically set the pump into @operationwhen the water `ffinany of the sumps has reached a prede'- Aterminedlevel. LA lrtlier object of my in vnitien is to provide, inadevice oi tlie class fmentioned, means whereby eacli etmop will be cutfrom .the `pump line tlie water :in the same has been practically exhausted. Af-if'rther object ofmly invention is to provide .fini-a,V pumping-device of the class men- @tionedl means: whereby the portion tliereoi3 at each sump may be adjusted to accommode e the seme-to the rate of flow' ci? weter into the sump. -Otlier objects will eppear tiere-ln latter. v f

I With-these objects in view my invention lo consists generally in' it meter d ven pump 'connected to' e; pump-lineend t meter con trolled "by efcircuit equipped with e, switch, lebranch pipeleedifng from tlie pump line toeacli sump, e'velvein'eecli lit ancli line,

the portion of the deviceerranged at each Sump,

Fig 2 is e perspective view, partially loroken away, of the valve end valve operatf ing mechmlism,

3 is a, vertical transverse section. through the valve on substantially the line 3*?) of il, and

l is ya detail liorizontal section on substantially the line 1l-#l oi Fig. 1.

Relterring now the drawings l indicates e pump of any ordinary or preferred form and 2 meter for operating the saine. Connested t e pump l. is the main pump line l l vdiicli is adapted 'to serve a plunty lo pipes ll, eacli leerling to a sump or pit (inly one sump and its reepective pipe i sliown, the general arrenggemen" n *lading a plurality of sumps is .well lino" i tlie erta,

.lrranggeri at eeclfi sump is :i 'valve casing tl 'Which-may comprise e, wooden loloclr hava trensverse horizontal 'Tin which is rotatable valve 8 which may also lee ci? "rooda The valve casing '6 is proja longitudinally arranged bore partially through the seme and communicating; with e.. downwardly extending bore l0. The end ci the bore 9 is connected to tlie branch pipe 'l and the end of the poition l0 with a pipe el extending subto the bottom of tile sump where may lee provided with strainer 11, for obvious reasons. 'llie valve 8 is provided with e, transveree "core which, whell tle votive is one pesition., registers with the "core ll sind when the velve is in another poJ- tion, closes the pemagewey through seid Hbore to tlie pipe Il., Fixed to the opposite ends ci the valve member is e pair of arms `These are rotatelily iixedwto the velve member as liy pins lll and the'free ends oseicl arms extend considerably beyond the end of the valve casing 6 and are secured to a Hoet liloclr l5. The float block l5 ie provided with a plurality of vertically dispo-sed 'hores lll which, in a large measure, becoming Iwater sorted.

is obvious that witlyL the above construction, vvlien the Awater in the sump rises, the float l5 will rise, and in rising, will open'r the valve 8; also that es tlie water is pumped out of the sump the Heat will drop thereby closing the valve @ne ottlie objects of my invention is to provide means whereby, asthel Water rises in the sump, the motor will be set into operation, and to this end l equip the electric circuit of the motor, which operates the pump, Withwawivitch, or air of contacts, at each sump whereby the rise and y fall of the float in the sump will make or threaded apertures 26, the purpose of which vwill be riti titl

break the circuit to the motor; and s o ar-r ranged that the device at each sump may close the circuit to start the pump into op eration.' Referring to the drawings 17 and i8 indicate the lines ofthe circuit to the motor 2, and i9 the source of electric supply. Arranged at each sump is a jumper pole provided with a suitable support permitting of vertical reciprocation of the pole. The pole is provided with a contact ,memberQl connected as at' 22 Withone line ofthe motor circuit and adjacent thereto is a g contact 23 which is Connected as at 2d with the other line of the circuit. It is obvious 'that by moving the pole upwardly the contacts are brought into engagement therewith closing the circuit and starting the motor driven pump. The lower end of the jumper pole 2 0 is preferably bifurcated as indicated at and provided with a plurality of resently described. Fixcd'to the. float l5 1s an arm 27 which is preferably in the form of a loop as shown encirclino one portion of the bifurcated end 25 of the jumper pole. 28 indicates a pin adaptedto be arranged in the apertures 26 and this is.

' preferably in the form of a thumb screw as indicated clearly in Fig. d. When the oatV rises 'the member 27 engages under the pin V 28 andraises vthe jumper pole to bring the contacts 21 and 23 into engagement. When the float drops it engages a transverse member and drops the'jumper pole to disengage the contzurts.V To this end a second pin, .28',

fina-y be employed but l prefer to have the valve and its casing l provide an annular gasket 30 at each .end of the valve which is preferably seated in a groove 31, formed in the valve end and adjacent portion of the l casing and these gaskets are held in position by the adjacent ends of the arms 13 as shown clearly in Fig. 3.

lFrom the foregoing-description it will be clcarjthat as soon as the 'Water rises in any-` suinp in the mine the respective oat will necesi? rise and close the contacts 21 and 23 thereby starting the pump into operation. llhen the Water has been,y pumped from -this particular sump the contacts will be separated,

as above' described; but the circuit to the 70 motor will not be brokenuntil the water in all of the sumps has been reduced to such an extent as to disengage all of the contacts. It should be noted that by providing the plurality of apertures 26, the pin ,28 may be set 7 5 so as to bring thedevice into operation when the water has reached any desired level in any particular sump and this is advantaA geous owing tothe fact that some sumps in a mine will fill more rapidly than others. It should also be noted that the valve will open the branch line proportionately to the amount of water in the sump.
